Besties share everything — clothes, secrets and, in the case of Miley Cyrus and Taylor Swift, boyfriends. Wait a second, though — it's not at all what you think.

For Taylor Swift's new music video for her song "You Belong With Me," Miley lent Taylor her "Hannah Montana: The Movie" onscreen love, Lucas Till, to have as her own for the clip.

Lucas — who took to his MySpace blog to announce the good news — said, "I may or may not have been shooting a music video for Taylor Swift. I may or may not play the 'main guy' in the video and he may or may not be the captain of the football team."

Have you ever gotten a new cell phone number and had to deal with getting all of the old owner's calls and texts about some awesome party this weekend? Yeah, well, Lil Jon feels your pain — except his calls are coming from Miley Cyrus' friends.

Lil Jon didn't say who has been calling him, but he did say that he's been getting awesome texts like "Congratulations on Teen Vogue!" So we're sort of wondering who has been calling Lil Jon thinking he's Miley.

Our first thought was Nick Jonas. He and Miley are broken up, so he might not have realized that she got a new phone number. Then again, the pair were recently seen going out to lunch (and getting into a minor fender bender) together, so he probably knows his ex's number. But we'd still like to hear Lil Jon's sage advice to the young Jonas brother on how to get crunk.

So which of Miley's many BFFs were still using the teen star's old number? Could it be Taylor Swift or Demi Lovato or Selena Gomez? We're going to assume that's not the case since they all Tweet with each other so often that they know how to find Miley and probably don't even need her phone number. We know it's not Justin Gaston. He is her boyfriend, after all.

Hmm... So who could it be? Why don't you tell us!

By now you've no doubt heard about Miley Cyrus and Nick Jonas' little lunch date/ fender bender in Los Angeles over the weekend. (Check out photos from the former couple's tarnished afternoon here.)

The real news here — clearly — isn't that the former couple had a lunch date. The big scoop, as far as I'm concerned, is that Nick's Mustang Cobra has fuzzy dice hanging from the rearview mirror. Very retro, classy touch on the part of young Mr. Jonas, I think. Nice car he's hanging them on, too.

I wonder what kind of ride Justin Gaston has going these days.

We usually leave the gaming to MTV Multiplayer editor Stephen Totilo but when he got his hands on the new "Hannah Montana: The Movie" video game, he decided to enlist the help of MTV News' resident Miley Cyrus fans.

Fellow Hannah-head Nicole Guanlao and I left our shame at the door and took on the challenge of testing out the Wii version of the game, which is based on the pop starlet's new film. The game follows the same plot as the movie: When her rock star alter ego starts going to her head, Miley Stewart is taken home to Tennessee by her dad, Billy Ray, in an attempt to get her back to her country roots.

Miley Cyrus must have been feeling very New York when she was getting dressed for a special screening of "Hannah Montana: The Movie" on Tuesday in Times Square. The usually colorful teen queen rocked all black for the screening. And it seems that the rest of the cast decided to follow suit. Both Emily Osment and Miley's onscreen cowboy boyfriend, Lucas Till, embraced the city's unspoken dress code.

Miley, who usually opts for white or more easy, breezy colors when she attends events, wore a black romper, thick black tights and boots. She accessorized the hard-edged look with a thick black belt and lots and lots of bracelets. She softened the look by wearing her hair down in loose curls.

Unfortunately, Miley did not bring the best accessory of all, boyfriend Justin Gaston. Oh well, there's always another day and another red carpet for which she can dress up her model/musician. (Check out a shot of Miley with her co-stars after the jump, plus browse the "Hannah Montana: The Movie" screening gallery.) Read more...

When Miley Cyrus sat down to write her new autobiography, "Miles to Go" (if the megastar ever actually takes the time to sit in one place these days), she made a decision to include some info on her breakup with Jonas Brother number three, Nick Jonas. She calls him "Prince Charming" in the book (um, I think feel a cavity forming). "I would say that it was hard, but it was also the best thing I ever did," she told MTV News.

Right on, girl! Bonus points for putting your heart out there in the book. So Miley clearly has a favorite JoBro. Or, uh, used to.

Suddenly the MTV Newsroom was debating the relative merits of each Jonas Brother and who deserved to be her (or anyone's) "favorite." Seriously. After we argued for a while, we decided to let the true experts — you, the fans — decide.

So cast your vote now in our non-binding, non-scientific, ultra-important poll.

Miley Cyrus is quite candid in her interviews — and she knows it. "I have word vomit," she's said. She recently stopped by the "Johnjay and Rich" radio show, and she touched on every possible subject ever. At times, her comments verged on oversharing.

Here are some of the highlights from the interview.

On her much older celebrity crushes: "I'm a Brad Pitt fan as an actor. I don't necessarily think he's good-looking. If I tell you guys who I think are cute, they're lame people. Like, I think Harry Connick Jr. is so cute. In 'Hope Floats' or 'P.S. I Love You,' isn't he the cutest? Yeah, he is. I think Gerard Butler is 'Oh, my God.' " Read more...

Young starlets and pop singers seem to have finally decided that the novelty of date a Jonas Brother has worn off. Just recently, Emma Roberts told Teen Vogue that although she once coveted youngest brother Nick, these days he's "a little tainted."

"I used to have a crush on Nick, but he's kind of making his rounds in Hollywood," she said, according to TeenVogue.com. "And I don't know if I like that."

Also, let's not forget the time that Selena Gomez, also a former lady friend of Nick's, warned the boys to stop dating the girls they put their videos (girls like her and Joe's maybe GF Camilla Belle). "Just put boys in [your] videos from now on; how 'bout that?" Read more...

In a preview of the music video for "Hoedown Throwdown" from "Hannah Montana: The Movie," Miley Cyrus sets out to show the world how she's "gonna add a little hip-hop to this hoedown!" The clip is basically an instructional video for fans to learn the moves so they, too, can hoedown like Miley. Moves including popping it, locking it and polka-dotting it. Sound fun?

If that weren't enough of a preview for you Miley fans, earlier this week, MTV News chatted with one of Miley's "Hannah Montana: The Movie" co-stars, Adam Gregory, who also stars on "90210." "I play the high-school crush for Miley's friend Lily. He's the guy that they can't get, and when he goes for Hannah Montana, he makes her resent Hannah."

Did you hear? BFFs Miley Cyrus and Taylor Swift will be singing a duet together at this Sunday's Grammy Awards! It's so OMG-worthy, I can barely stand it!

Taylor has given some work to Miley's boyfriend, "model" and "musician" Justin Gaston, when he starred in her video for "Love Story" and then reprised the role for her performance at the CMT Awards. And the two have probably bonded about their Jonas Brothers exes (who, by the way, will also be at the Grammys.) But it's about time that the ladies join their combined teen-star forces.

According to Ryan Seacrest's Twitter, he pair will sing "Fifteen," from Swift's seemingly unstoppable album Fearless. I want to be quick to point out, though, that neither Taylor nor Miley is nominated for a Grammy this year, which makes it kind of awkward that they're gracing the stage — although it's a big ratings win for the Academy. The kids just want to see their favorite singers together on one stage!

It will be interesting to see what these two pop stars have up their sleeves. And, it'll be fun to see if Justin Gaston manages to squeeze in on the act. I wait with baited breath. But, really the next big question that springs to mind is: What are they going to wear? Will they match? Only time will tell.
